'rnrnoven CARPET-smeren.

TO ALL WHOM IT MAY CONCERN:

viBe it known that we, GEORGE PURRINGTON, Jr., of the city, county, andState of New York, and JAMS'H. PURRINGTON, of Mattapoisett, in thecountyof Plymouth,'and State of Massachusetts, Ihave invented a new anduseful Improvement in Carpet-Sweepers; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, whichl willenable others skilled inthe art to make and use the same, referencebeing had to the accompanying drawings, forming part of ythisspecication, in which- Figure 1 is a vertical cross-section of ourimproved carpet-sweeper taken through the line m gv, fig.'I 4. Figure 2is an end view of the same. A Figure 3 is a detail sectional view of thesame taken through theline gig, tig. 2."

Figui-e4 'is a longitudinal section of the same taken through the line zz, g. 2, the middle Dart bein broken away to show the construction.

Similar letters of reference indicate like parts.

Our invention has for its'object to so improve the construction ofcarpet-sweepers as to make them more durable, and more reliable' inoperation. And it consists, `iirst, in the combination and arrangementof the cogged or corrugated wheel and two adjustable wheels` with eachother, and with the brush-shaft and frame of the sweeper; second, in theadjustable axles or bearings, in combination with the drive-'wheels andframe of the sweeper the` whole being constructed and arranged ashereinafterjmore fully described.

A is the frame of the sweeper, to the upper edges of which is attachedthe roof-shaped cover, B. C is the brush-shaft, to which the brush H isattached in the ordinary manner, and which is pivoted to the adjustablebearings D, which are secured tothe end pieces of the frame A by screwspassingthrough slots iin'said bearings, and screwing into said endpieces, as shown in iigs. and 4. To the bearings D are also pivoted thebranched ends of the iron frame, E, to which the handle, F, is attached.Gare the dust pans,`which are pivoted to the end pieces of the frame, A,in such positions-as to receive the dust and dirt raised bythe brushesH, and which'are held in their places by the catches I, attachedto thesides of said pans, and catching upon the side pieces of the frame A. Jare the drive-wheels, which 'are small wooden or metallic Wheelssurrounded with thick rubber bands, and which revolve upon axles orbearings K, the plates of which are ladjustably attached to the endpieces of the frame A, and which are secured in place by screws, thelower ones of which pass through slots in the lower parts of saidbearings, as shown in lig. 2, so that the said drive-wheels J may beadjusted to compensate for their wear, and may be always kept in aproper working position with respect to the other parts. TliedrivewheelsJ must vbe so placed as to project a little below the lower edges of theframe, A, so as to come in contact with the carpet over which'thesweeper is drawn, and be revolved by said contact. L is a small toothedor corrugated wheel, placed upon or attached to the end of thebrush-shaft C, and which comes in contact with and is revolved by thedrive-wheels J, and carries with it the brush-shaft C. g 4M is a shoeplaced upon the loweedge of the end piece of the frame A, opposite tothe drive-wheels C,upon which that end of the sweeper slides, and whichkeeps the sweeper in a horizontalposition while being used. v

We do not claim any of the parts the subject-matter of' the patentsgranted to Daniel Harris, October 5, 1858, and S. W. Smith, January 18,1859, but what we do claim isi The adjustable axles or bearings K,"constructed and arranged substantially as herein described, incombination with the drive-wheels J, and* frame A, of the sweeper, asand for the purpose herein set forth.
